It looks like there might be some confusion or misinformation here. As of my last update, Carlos Alcaraz and Novak Djokovic are both top professional tennis players, but they compete individually and have their own teams. There hasn’t been any announcement of Carlos Alcaraz becoming a captain for Novak Djokovic or vice versa.
If this is a recent development or a specific context (like a team event or a special project), I might not have the latest details. Can you provide more context or specify where you saw this announcement?
